Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical fiber connector device for connecting a photoelectric element and an optical fiber.

[0002]

2. Description of the Related Art A conventional optical fiber connector device is constructed, for example, as shown in FIGS.

25 and 27 are perspective views of the optical fiber side housing in different states.
Reference numerals 6 and 28 are cut-away right side views of the optical fiber side housing with parts removed corresponding to the states of FIGS. 25 and 27, respectively.

The optical fiber side housing 1 has a thin hollow structure, and the optical fiber 2 is integrally formed with the grip portion 1a on the rear end side.
The threaded screw portion 1b of the mounting body 4 for mounting the protective tube 3 is formed, and the front end portion of the optical fiber 2 inserted into the tube 3 mounted on the mounting body 4 is inserted into the optical fiber side housing 1. A small housing hood 5 having a rear surface opened at a connecting portion 1c with a module side housing (not shown) on the front end side of the optical fiber side housing 1.
Are slidably mounted along the guide recess 1d. Although not shown in the drawing, the hood 5 is the connecting portion 1.
An engagement mechanism is provided on the hood 5 side and the coupling portion 1c side so as not to separate from c.

Further, the ferrule 6 into which the front end of the optical fiber 2 is inserted is disposed inside the hood 5 and attached to the coupling portion 1c of the optical fiber side housing 1, and when the hood 5 slides rearward, the ferrule 6 is inserted. A through hole 7 is provided in the front side surface of the hood 5 so that the tip of the hood 6 projects from the hood 5. Before sliding the hood 5 backward, the ferrule 6 is completely immersed in the hood 5. The end face of the optical fiber 2 is protected by the hood 5, and the front end of the ferrule 6 is projected to the outside of the hood 5 by sliding the hood 5 backward. When the module side housing (not shown) is coupled, the photoelectric conversion inside the module side housing is performed. The end face of the optical fiber 2 can be connected to the element.

By the way, two elastic pieces 8 each having a front end urged upward and downward are integrally formed on both upper and lower surfaces of the coupling portion 1c of the optical fiber housing 1, and each elastic piece 8 has a front end. Since the thickness of the portion is thicker than the rear end, the front end of the upper elastic piece 8 is higher than the upper surface of the hood 5, and the front end of the lower elastic piece 8 is lower than the lower surface of the hood 5. When the hood 5 is projected downward and before the hood 5 slides backward, the rear surface of the hood 5 contacts the front surface of each elastic piece 8 to prevent the hood 5 from sliding rearward, as shown in FIG. The front end of the ferrule 6 is prevented from protruding outside the hood 5, and the end face of the optical fiber 2 is protected.

On the other hand, when the optical fiber side housing 1 is connected to the module side housing (not shown), as shown in FIG. 28, the front end portion of each elastic piece 8 resists the urging force of the hood 5 prior to the connection. The hood 5 is slid rearward so that the front end of the ferrule 6 is deformed until it enters the inside.
Is projected to the outside.

Elastic locking pieces 9 are integrally formed on both left and right sides of the optical fiber side housing 1 so as to extend rearward, and a protrusion 10 at the center of the locking piece 9 is formed at an engaging portion of the module side housing. By engaging with the optical fiber side housing 1 and the module side housing, the photoelectric element accommodated in the module side housing and the front end of the optical fiber 2 inside the protruding ferrule 6 are connected. When the optical fiber side housing 1 and the module side housing are separated, both elastic locking pieces 9
By deforming the rear end portion, the engagement of the protrusion 10 is released, and by sliding the module side housing forward, it is possible to separate the optical fiber side housing 1 and the module side housing.

At this time, although not shown, when separating the module side housing, the hood 5 is slid forward by an elastic biasing member provided between the optical fiber side housing 1 and the hood 5. The hood 5 returns from the state of FIG. 28 to the state of FIG.
Is restored to the state before deformation, and the rear surface of the hood 5 has elastic pieces 8
And the ferrule 6 is held in the hood 5 so that the end face of the optical fiber 2 is protected.

[0010]

However, as described above, the hood 5 is slidably provided directly on the coupling portion 1c of the optical fiber side housing 1 and the ferrule 6 is attached to the hood 5 when the two housings are separated from each other. When the end face of the optical fiber 2 is protected by being covered with the end face of the optical fiber 2 even if the ferrule 6 is immersed inside the hood 5, the end face of the optical fiber 2 is completely removed from the through hole 7 of the hood 5. When the end face of the optical fiber 2 cannot be protected and the elastic piece 8 is deformed to move the hood 5 backward as shown in FIG. There is a problem that the piece 8 is plastically deformed and loses the restoring force, and the hood 5 easily moves and cannot play the role of protecting the end face of the optical fiber 2.

Further, dust easily accumulates in the guide recess 1d of the coupling portion 1c, and the hood 5 cannot slide smoothly.

Therefore, the present invention has been made to solve the above problems, and an object thereof is to make it possible to surely protect the end face of an optical fiber.

[0013]

The housing is formed on both side walls of the connecting portion of the module-side housing, and when the housings are connected, the hood body is rotated in the exposing direction of the end surface due to the sliding contact of the inclined surface of the lower portion of the hood body, thereby separating the housings. It is also effective that the hood body is rotated in the covering direction of the end face by the downward movement of the guide pin due to the sliding contact of the closing operation body.

[0016]

Conventional nor the rotation of the hood body is prevented by the dust or the like.

Further, when the two housings are joined together, the lower part of the hood body is slidably contacted with the inclined surface of the opening actuating body so that the hood body is rotated in the direction of exposing the end face of the optical fiber, and the guide pins are closed when the two housings are separated. The hood main body rotates in the covering direction of the end face of the optical fiber due to the downward movement of the guide pin caused by the sliding contact with the end face of the optical fiber.

The ferrule 22 is biased to prevent the ferrule 22 from moving rearward.

27 is an optical fiber side housing 13
Two protrusion-like locking pieces integrally formed on the upper portion of the coupling portion 23 of the above, 28 are disposed on the coupling portion 23, and the rotation shafts 29 on both sides are provided.
Is inserted into the through holes 30 on both side surfaces of the coupling portion 23 and rotatably attached to cover and expose the end surface of the optical fiber 14. A hood body having an arcuate cross section is provided. The two arc-shaped elastic bodies 32, which extend upward along the side surface of the two and are integrally formed, are integrally formed on the locking claws 32 ′ at the upper ends of both elastic bodies 31, and the locking pieces 2 are formed.
Two locking bodies, 33, which are abutted against 7 and pushed down to the lower side of both locking pieces 27 by sliding contact of both pressing pieces 18 when the two housings 11 and 13 are coupled, are two guide pins. The hood body 28 is integrally formed at the lower ends of the left and right side surfaces of the hood body 28, and moves upward due to the sliding contact of the opening actuating body 16 when the housings 11 and 13 are coupled.
Is rotated in the exposing direction, which is the opening direction, and when the housings 11 and 13 are separated, it is moved downward due to the sliding contact of the closing actuating body 17 and is rotated in the covering direction, which is the direction in which the hood body 28 is closed.

As is apparent from FIGS. 1 and 13, the positional relationship between the opening actuation body 16 and the closing actuation body 17 of the module side housing 11 is such that the opening actuation body 16 is located in front of the closing actuation body 17, that is, the photoelectric element. 12 and the closing actuator 17 is above the opening actuator 16,
As can be seen from FIG. 5, an escape groove 34 is formed below the closing operation body 17 so that the guide pin 33 on the right side of the hood main body 28 in the covered state does not contact the closing operation body 17. Since the right guide pin 33 passes through this clearance groove 34 when the housings 11 and 13 are coupled, the guide pin 33 does not move upward at the beginning of coupling, and the left guide pin 33 does not move to the rear surface of the opening actuating body 16. Only when the two housings 11 and 13 are connected to each other until the housing comes into contact with the guide pin 33, the guide pin 33 starts moving upward, and the hood body 28 rotates in the exposing direction.

Reference numeral 35 denotes the optical fiber side housing 13
An extension piece integrally formed by extending forward from the rear end of the upper surface of the upper end to almost the center, and 36 is a retaining engagement projection formed at the front end of the extension piece 35, which joins the housings 11 and 13 together. At times, it engages with the engaging portion 19 and the module-side housing 1
1 is prevented from coming off, and when the housings 11 and 13 are separated from each other, the pressing portion 37 at the rear end of the extending piece 35 is pressed to disengage the engaging projection 36 from the engaging portion 19, so that the housings 11 and 13 are separated. Become separable.

Next, the operation of connecting and disconnecting the two housings 11 and 13 will be described.

First, the case where the two housings 11 and 13 are joined together will be described. By moving the optical fiber side housing 13 forward from the state shown in FIG.
As shown in FIG. 7, the pressing pieces 18 are brought into sliding contact with the locking bodies 32, respectively, and the elastic bodies 31 are deformed, so that the locking bodies 32 are pushed down to the lower sides of the locking pieces 27.

When the optical fiber side housing 13 is moved further forward, the guide pin 33 slides up against the rear surface of the opening actuating body 16 and moves upward as shown in FIG. The end face of the optical fiber 14 is exposed by rotating in the exposing direction, and as shown in FIG. 11, the tip of the ferrule 22 is introduced into the introducing part 15 and the end face of the optical fiber 14 is tightly coupled to the photoelectric element 12 and, at the same time, engaged. Both housings 1 by engaging the mating protrusion 36 and the engaging portion 19
The separation of the housings 1 and 13 is prevented, and the coupling of the housings 11 and 13 is completed.

At this time, as is apparent from FIG. 11, when both housings 11 and 13 are completely connected and the hood body 28 is rotated in the exposing direction, the two locking bodies 32 are connected to the rotation shaft 29 of the hood body 28. Since they are rotated to the same low position, no external force is applied to both locking bodies 32 and both elastic bodies 31, and the optical fiber connector device is used for a long time in a high temperature environment in such a state. However, neither elastic body 31 is plastically deformed.

Next, the case of separating the two housings 11 and 13 will be described. By pushing down the push-down portion 37 and pushing down the entire extension piece 35, the engagement between the engagement projection 36 and the engagement portion 19 is released. Therefore, it becomes possible to move the optical fiber side housing 13 rearward, and by moving the optical fiber side housing 13 rearward,
As shown in FIG. 12, the guide pin 33 causes the closing operation member 17 to move.
Of the hood main body 28 is rotated in the covering direction, and further the optical fiber side housing 13 is moved rearward so that the right guide pin 33 is below the closing operation body 17. The guide pin 33 on the right side enters into the escape groove 34 on the right side while being restrained by the groove 34.
Slide backwards inside.

At this time, the guide pin 33 on the right side is inserted into the groove 34.
Upon entering the inside, both locking bodies 32 project forward from the lower side of both locking pieces 27 and come into contact with the front surfaces of both locking pieces 27, and the contact of both locking bodies 32 causes the rotation of the hood body 28. The end face of the optical fiber 14 is reliably covered by the hood body 28.

Then, as shown in FIG. 13, the optical fiber side housing 13 is moved further rearward to complete the separation of the two housings 11, 13.

Therefore, according to the first embodiment, the hood main body 28 rotatably provided on the coupling portion 23 of the optical fiber side housing 13 is exposed as the two housings are coupled and separated.
Since the end face of the optical fiber 14 is exposed and covered by rotating in the coating direction, the end face of the optical fiber 14 can be completely covered and protected in the separated state, and in the coupled state, the elastic body as in the prior art can be used. No external force is applied to 31 and it is possible to prevent plastic deformation of the elastic body 31 even when it is used at high temperatures, and there is no fear that dust will impair the smoothness of rotation of the hood body 28 as in the conventional case.

(Second Embodiment) FIGS. 14 to 23 show a second embodiment of the present invention. 14 and 15 are a perspective view and a rear view of the module side housing, FIG. 16 is a perspective view of the hood body separated from the optical fiber housing, and FIG. 17 is a view of the hood body rotated in the covering direction. FIG. 18 is a perspective view of the fiber-side housing, FIG. 18 is a cut right side view in a state where both housings are separated, FIG. 19 and FIG. 20 are a cut right side view in the middle of coupling both housings, and FIG. 21 is a cut right side in a coupled state of both housings. 22 is a cutaway right side view of the two housings in the middle of separation, and FIG. 23 is a cutaway right side view of the two housings in a separated state.

In the second embodiment, both housings 11,
The structure of 13 is almost the same as that of the first embodiment, but there are the following differences.

That is, the difference in the module side housing 11 is that, as shown in FIGS. 14, 15 and 18, instead of the opening actuating body 16 in the first embodiment, the coupling portion 11b is provided on the upper side of the introduction portion 15. The opening actuating body 41 having a downward inclined surface toward the opening side is formed, and instead of the closing actuating body 17 in the first embodiment, a rear end is formed in the upper half of both left and right inner side walls of the coupling portion 11b. This means that the closing actuating body 42 that is bulged inward is formed from the to the vicinity of the central portion of the coupling portion 11b, and the closing end of the closing actuating body 42 is formed with an inclined surface that extends downward and rearward.

On the other hand, the difference in the optical fiber side housing 13 is that, as shown in FIGS.
Is formed at a position slightly lower than the locking piece 27 of the first embodiment, and unlike the elastic body 31 of the first embodiment, two linear elastic bodies 45 are diagonally upward on both left and right sides of the hood body 28. To be formed integrally with each other, and at the upper ends of both elastic bodies 45, locking claws 46 similar to the locking claws 32 'of the first embodiment are formed, respectively, and both locking claws 46 are integrally locked. That is, the body 47 is formed.
When the housings 11 and 13 are joined, the pressing pieces 18 are slidably contacted with each other and are pushed down to the lower side of the locking pieces 44.

Then, in this way, both housings 11, 1 are
When both locking bodies 47 are pushed down to the lower side of both locking pieces 44 during the coupling of 3, the hood body 28 rotates slightly in the exposing direction, and the lower portion of the hood body 28 slides on the inclined surface of the opening actuating body 41. In this state, the hood body 28 rotates in the exposing direction with the sliding contact of the lower portion of the hood body 28, and when the two housings are separated, the guide pin 33 slides on the inclined surface of the closing operation body 42 to guide the guide. The pin 33 moves downward, and the hood body 28 rotates in the covering direction as the guide pin 33 moves downward.

Next, the operation of connecting and disconnecting the two housings 11 and 13 will be described.

First, the case where the two housings 11 and 13 are joined together will be described. By moving the optical fiber side housing 13 forward from the state shown in FIG. 18, as shown in FIG. Both ends are both locking bodies 4
The two elastic bodies 45 are deformed and the two locking bodies 47 are pushed down below the two locking pieces 44.

Then, when the optical fiber side housing 13 is moved further forward, as shown in FIG. 20, the lower portion of the hood main body 28 is brought into a state in which it can be slidably contacted with the inclined surface of the opening actuating body 41, and the optical fiber side housing. With the forward movement of the hood 13, as shown in FIG. 21, the lower portion of the hood body 28 slides on the inclined surface of the opening actuating body 41 to rotate the hood body 28 in the exposing direction, and the tip of the ferrule 22 is introduced. The end face of the optical fiber 14 introduced into the portion 15 is the photoelectric device 1
2, and the engaging projection 36 and the engaging portion 19 are engaged with each other at the same time to prevent the housings 11 and 13 from being separated from each other.
The joining of the two housings 11 and 13 is completed.

At this time, as is apparent from FIG. 21, the two housings 11 and 13 are completely connected and the hood body 28
In the state in which the locking members 47 are rotated in the exposing direction, both locking members 47 are rotating to a low position at the same height as the rotation shaft 29 of the hood body 28 as in the case of FIG. No external force is applied to the elastic bodies 45, and even if the optical fiber connector device is used for a long time in a high temperature environment in such a state, neither elastic body 45 is plastically deformed.

Next, the case of separating the two housings 11 and 13 will be described. By pushing down the push-down portion 37 and pushing down the entire extension piece 35, the engagement between the engagement projection 36 and the engagement portion 19 is released. Therefore, it becomes possible to move the optical fiber side housing 13 rearward, and by moving the optical fiber side housing 13 rearward, the guide pin 33 causes the inclined surface of the front end of the closing operation body 42 as shown in FIG. 23, and the hood main body 28 rotates in the covering direction accordingly, and further moves the optical fiber side housing 13 rearward. As a result, as shown in FIG. Both locking bodies 47
Is released from the state in which it is pushed down to the lower side of both locking pieces 44, and the rear surfaces of both locking bodies 47 come into contact with the front surfaces of both locking pieces 44, respectively, and rotation of the hood body 28 is prevented. , The end surface of the optical fiber 14 is surely covered by the hood body 28, and the optical fiber housing 13 is moved further rearward so that both housings 1
Separation of 1 and 13 is completed. Therefore, according to the second embodiment, it is possible to obtain the same effect as in the case of the above-described first embodiment, and the closing operation body 42 is provided on both inner side walls of the coupling portion 11b of the module side housing 11. With this structure, the hood body 28 can be more smoothly rotated in the covering direction as compared with the first embodiment in which only one is formed.

As a third embodiment, as shown in FIG. 24, the upper portion of the introducing portion 15 is used as an opening actuating member 51, and the rearward and front ends of the opening actuating member 51 are inclined toward the rear side 52 ,. Each 53 may be formed.
